3D Printing for Large Scale Trains – #2 The Prusa Experience

If you missed the first part in this short series, read it here: 3D Printing for Large Scale Trains – Introduction.

In the previous post, I mentioned purchasing a pre-assembled Prusa i3 MK3S+ printer from the highly regarded Czech company Prusa Research. The printer comes with everything you need to get started, and for real, you can be printing within an hour.

Right off the bat, prints have been great. I had to slightly adjust the “Live Z” value to finetune the quality of the first layer, but this was easily done. I started using leftover PLA filament from my previous printer (Velleman), and apparently this filament was very prone to stringing, even when using lower temperatures and increasing retraction. I just gave up on it, and ordered Prusa PLA, and the stringing is minimal now. So I’ll use the Velleman filament only for prototyping from now on, and take the Prusa filament for “production” prints.

Very little tuning, very consistent print quality, I am very glad the printer is delivering on all the promise so far.

First project: dusting off the Feldbahn freight car project I designed six years ago in Sketchup, and building it again from scratch in Autodesk Fusion 360. More details in a next post in this series.
